Fig. 2 i3 :t similarview illustrating u, rlilfcm'nl'. o'rm nf `tlm bearing.

und Fig. 49El specitni'lfi nfmiernmnu noY 60 l5 without anyr provision against lateral dis- 7 und 8 plates are arranged at a slight angle to each other to maintain their inner faces.` apart. Fis. 5 and 6 show .the plates I0 and 11 wit segmental, recessed portions 25 and segmental projecting portions 26. The recesscd portions 25 of the lower plate, for example, are adapted to copcrate with the corresponding injecting portions 26 ,o'f the upper plate, wliich projecting portions are somewhat higher than the depth of the recessed portions 25, whereby the inner faces of said upper recessed portions and of the lower projcctingfportions will be held a slight cistance apart,'as shown. In Figs. 'T and 8, the plate 10 is provided with projections 30 adapted to t corresponding devressions 31 formed in the upper plate 11, ut of a depth slightly less'than the height of the said projections 30, whereby the inner faces of the said plates will be maintained a slight distance apart. The means above described in connection-with Figs. 1, 5, 6,

rovide,also, forthe positive centering oij the ilates, so that an accurate hearing is produced. In the constructions illustrated in Figs. 2, 3 and 4, the plates 10 and 11 are centered by forcing one plate within the flanged or turned over portion of the other. A

Fi 3, 4, 9, 10 and 11 illustrate a bearing in' which the 'flared portion of the plates 10 and.11 extends. slightly beyond the center of thc balls 17, so that the sameare retained by the bearing itself, and-no sleeveis required as in the usiial'forni of bearing. To apply a bearing of this character, with re.-

tained balls, to a shaft, as -for example to thc shaft 15, Figs. 3 and 4:, the said shaft may be provided with a conical shoulder 35 against which the said bearing is made to abut. The bearingis heldthereto by means of a suitable collar 36 provided with conical eind 37 fitting' in against the balls 17'and held in place on the shaft 15 by a' suitable 'set screw. 38,' or the like. In Figs. 9 to 171,

the hearing is illustrated with an extenda attaching sleeve o'r member 40 composed o two ortions ,41fand 42, the former extending" rom andbcing intefrral with thelplate 10, and the latter similar y extenda from the plato 11 and ecpcrating with the ormcr to provide the sleeve 40. A bearing with such attaching member is suitable for use in connection with trcadle mechanism, for

example a's shown in Fig. 11; and in which a treadle' 43 is connected with the same through a connecting rod 44 held within sleeve 40 in any 'suitable manner, as by means of a set screw 45. -The bearing in this application is simply placed over shaft placement, being lield in substantially one position on the said shaft by the said treadle mechanism.

It is evident that various means may be employed to maintain the said plates a slight distance apart for the purpose set forth, as well as to center the same; .and tho invention is not restricted to the specific means vherein set foi-th. The attaching means' illustrated in connection with the bearin provided with the retained balls may a so be-varied without departing from the spirit of the invention.

We claim:-

1. A two-piece ball bearing com rising: two apertured plates, slightly yielda le rclatively to each other provided with means whereby the said plates are maintained a slight distance apart'ancl a'ordng an an' nular raceway, a Asingle set of balls h eld between said plates lin said raceway and substantially .in contact with each other and means between thc circumference of 'soi plates and the said set `of 'balls to draw the `former together to provide the desired presbetween said plates in said iaiceway, and

substantially in contact Ywith cach other, and adjustable means between the circumference of said,`v plates and the said set'wof balls to ctlraw the; fornier-togetherto provide the esiredressure upon the latter.

3.4i ,limpiece ball bearing comprising: two/apertured plates, slightlv yieldable relatively to; eac li'other, provi red with means whereby the saidfplts are maintained a slight distance apart and ali'ording an annular. raceway, a single set of balls held between said plates in" said raceway und substantially in vcontact with each other means between the; circumference' of sai plates and the said' set of balls to draw the formertogfether to proiide the desiredv pressure uponthe latter, and means to positivelv center said plates.

4.- A self-contained ball bearing comprising two apertured plates alording an annular raceway d two re'steiingapertures in the said raceway and the bearing bas substantially in contact withV each othei",he distancebetween any'two diametrieell bpposed balls theeof bein less than/tho d1 ineter of a 4single ball, wereby the said alle are self retained, sind means to secure said plates to each other. y y

5. A self-contained ball bearingmcoz'iiprising two lapertureil plates a'ordin'g an annula: aceway and tw'o re tering apertures, a single sct of balls held etween said plates in said raoeway and the healing balls substantially in contactA with each other the plates extending beyond the center ci the a single set of balls held between sind plates in the said raceway and the bearing balls substantially in Contact with each other, tbe distance between any two .diametrically opposed lm lls thereof being less than the dlameter olma single ball, whereby the said balls` are self-retained`r means to secure said plates` te earh other, and atlarhinlelr means extending from said bearing'.

- 7. A self-contained two-piece ball hearing enniprising two apertured plates, slightly vieldalile relatively lo eau-h other, provided with means whereinv the said 4plates are maintained a slight distance apart and af l'ording an annular racewalv and two registering apertures: a single set of balls held between said plaies in the said raeewa)r and lhe bearing halls substantially in enntaet with each other, the distance between any two dialnetrieallir opposed balls thereof beinter less than the diameter of a single hall, whereby the l aid halls are sel lretained, and means to serine said plaies to eaeh other.

H. two-piece hall hearing comprising: two apertnred plates1 slightly yieldalile rela tively to eaeh other alnlihaving means interral (herewith to maintain said'plates a slight cl'islanee apa rt and affording an amullar rari-way, a single set el balls held be tween said plates in said raceway, and means between the circumference of said plates and the said set 0f balls to drawthe, ormer together to provide the desired pressure upon the latter.

9. A two-piece ball bearing comprising: two apertured plates, slightly yieldable relatively to each other and having means integral therewith to maintain said plates a slight distance apart and affording an annular raceway, a single set of balls held between said plates in said raceway, and adjustable means between the circumference of said plates andthe said set of balls to draw the former together to provide the desired pressure upon the latter.

10. A two-piece ball bearing comprising: two apertured plates, slightly yieldable relatively to each other and having means integral therewith to maintain :aid plates a slight distance apart and affording an annular racewa'y, a single set of balls held between said plates in said raceway, means between the eireumferenee of said plates and the said set ot halls to draw the former together to provide. the'desired pressure upon the latter. and means to 4positively center said plates. i
